Plastic tubing holder

ABSTRACT

A PLASTIC TUBE HOLDER FOR METALLIC TUBULAR FURNITURE WHEREIN A SINGLE LENGTH OF PLASTIC TUBING FORMS EACH OF THE BACKREST AND SEAT CONSISTING OF AN ELONGATED MEMBER HAVING A SLIGHTLY LARGER THAN SEMI-CIRCULAR CROSS SECTION, THE DIAMETER OF THE ELONGATED MEMBER BEING SLIGHTLY SMALLER THAN THE SUM TOTAL OF THE DIAMETER OF THE METAL TUBING FORMING THE FRAME PLUS THE THICKNESS OF THE FLATTENED PLASTIC TUBING ENCIRCLING THE FRAME TO PERMIT THE ELONGATED MEMBER TO BE SNAPPED IN POSITION OVER THE ENDS OF THE PLASTIC TUBING AT THE POSITION THEN ENCIRCLE THE METAL TUBING. THE ENDS OF THE ELONGATED TUBING BEING CURVED INWARDLY TO ENGAGE THE METAL TUBING AND PREVENT THE ROWS OF SPACED PLASTIC TUBING FROM BEING DISPLACED.

No. 786,238 Int. Cl. A47c 31 04 U.S. Cl. 297-452 1 Claim ABSTRACT F THE DISCLOSURE A plastic tube holder `for metallic tubular furniture wherein a single length of plastic tubing forms each of the backrest and seat consisting of an elongated member having a slightly larger than semi-circular cross section, the diameter of the elongated member being slightly smaller than the sum total of the diameter of the metal tubing forming the frame plus the thickness of the attened plastic tubing encircling the frame to permit the elongated member to be snapped in position over the ends of the plastic tubing at the position then encircle the metal tubing. The ends of the elongated tubing being curved inwardly to engage the metal tubing and prevent the rows of spaced plastic tubing `from being displaced.

This invention relates to aluminum furniture and is amore particularly directed to a plastic tubing holder for lawn chairs and the like.

A principal object of the present invention is to provide aluminum furniture having a backrest and seat each made of a single length of plastic tubing with a holder or clip to maintain the tubing in proper and neat position during use of the furniture.

Another object of the present invention is to provide aluminum furniture with an elongated metallic holder or clip having a greater than semi-circular cross section which is snapped into position over plastic tubing forming the backrest or seat of the furniture.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modied so long as such changes or modifications mark no material departure from the salientvfeature of the invention as eX- pressed in the appended claim.

In the drawing:

FIG. 1 is a perspective view of a conventional lawn chair using plastic tubing on which my holders are shown in position.

FIG. 2 is a detailed enlarged view of a portion of the backrest.

FIG. 3 is a cross sectional view taken along the line 3--3 of FIG. 2.

FIG. 4 is a cross sectional View taken along the line 4 4 of FIG. 3.

Referring to the drawing wherein like numerals are used to designate similar parts throughout the several views the number refers to a conventional lawn chair consisting of a tubular member 11 forming the frame support for the backrest B and a tubular member 12 forming the frame work of `the seatrest S. Both the tubing 11 and 12 are formed in a U-shaped with their free ends pivoted together by a rod 13. A pair of links 14 is like- .wise pivoted at one end to the rod 13 while the other end is pivoted by a pin 15 to the tubular member 16 which forms the rear support legs of the chair 10. The tubular member 16 is formed in a U-shape with its free ends pivoted as at 28 to a bracket 17 that is secured to the lower surface of armrests 18. The armrests 18 are pivoted at one end to the tubular member 11 by a pivot pin 19 that extends through a spacer 20 and a plastic tubing holder 30, the subject matter of the present invention and explained in detail hereinafter.

The forward portion of the lawn chair 10 is supported by legs 21 whose upper end is pivoted as at 22 to the bracket 17, and the mid-portion pivoted to the seat tubing 12 by pivot pins 23. The lower end of the legs 21 is strengthened by a brace 24 extending between the legs 21.

As in the instance of the pivot pins 19 which extend through a bore in the plastic tubing holder 30 and the tubular member 11, the pivot pins 23 each extend through a plastic tubing holder 31 and the tubular member 12, the plastic tube holders 31 being identical in construction and function with that of the plastic tube holders 30.

The backrest B is constructed by taking a single length of plastic tubing 25 securing one end by a screw 26 to the aluminum tubing 11 and then winding the full length of the tubing 25 from side to side on the backrest frame tubing 11 in slightly spaced rows until the backrest has been covered and the free end of the plastic tubing is secured to the tubing 11 by a similar screw 26 at the lower end of the tubing 11. Then my plastic tubing holders or clips 30 are `force-fitted over the plastic tubing ends where they encircle the backrest tubing frame 11.

The plastic tubing holders consists of a length aluminum material shaped to be formed slightly larger than semi-circular in cross section. In forcing the holder 30 into position, the plastic tubing 25 is compressed as shown by FIGS. 3 and 4 while the outer edges 32 of the holder 30 engage the flattened plastic tubing 25 beyond the tangential portiton of the metal tubing 11 to become secured thereon and from which a considerable force would be necessary to remove the holder 30 therefrom. The ends of the holder, or clip 30 is spun inwardly to form an inwardly curved or cupped portions 29 that engage the metal tubing 11 and prevent the displacement of the end rows of plastic tubing 25. The holder 25 is provided with a bore 33 for receiving the pivot pin 19.

The seatrest S is constructed in identically the same manner as the backrest B with a single length of plastic tubing 27 wound from side to side about the tubing frame 12 with the ends secured to one of the metal tubing 12. A plastic tube holder 31 identical to that of the holder 30` is force tted into position over the ends of the plastic tubing 27 to maintain the plastic tubing in an even coplanar position as in backrest B. The holders or clips 31 are likewise provided Iwith a bore 33 for receiving a pivot pin 23. The pivot pins 19, 23 prevent any longitudinal sliding movement of the plastic tube holders 30, 31 while its resilient wall structure permits the edge portions 32 to grip and hold the clips 30, 31 in position over the tubing 11, 12 while maintaining the plastic tubing flat against the tubing 11, 12. This results in the plastic tubing of the backrest and seatrest always remaining in coplanar relation with each row spaced slightly from and in parallel relation to its adjoining row. At no time can the rows of plastic tubing become displaced so that they cross each other or do the spaces therebetween become irregular no matter what forces tend to push the plastic tubing 25, 27 laterally as occurs when the chair 10 is in its normal use. The holders or clips 30, 31 maintain the attened end portions about the metal tubing 11, 12 in tight coplanar and contact relation so that one end portion cannot slide onto or over its adjacent end portion.

What I desire to secure by Letters Patent of the United States is:

1. In metallic furniture having a tubular frame for its seat and backrest with a single length of plastic tubing for each of the seat and backrest secured at one end to the tubular frame and `wound from one side to the other in spaced parallel rows encircling the tubular members forming the frame and securing the other end to said tubular frame, a plurality of elongated members having a slightly larger than semi-circular cross section telescopically mounted on said tubular members engaging said plastic tubing and forming llattened surfaces of said plastic tubing with each row in substantial contact with an adjacent row and said ends of said elongated member being curved inwardly to engage and encompass said outermost flattened tubular members whereby said rows of plastic tubing forming said seat and backrest are prevented from being displaced axially thereof, said elongated members having an opening for receiving a pivot pin to prevent the axial sliding movement of said elongated members on said tubular members.
